my homepage was changed to some anti spyware thing but i think this was fake had it before. also computer kept crashing when ui clicked on internet explorer have managed to get on net using mozilla.
Try a "restore" on your computer to an earlier time when you knew everything was ok. This will restore the settings from that time and might cure your possible non-existant virus?
Click on " start" then " search" " all files" and type in the word restore and click on search. It is usually the first in the list that appears as System Restore.
If you click on this it will open a window which allows you to click on a date when the computer last set a restore point.
Click on this date and ask it to restore. It will take a couple of minutes and restart your computer automatically with a note to say it has been restored to that date. If it doesn't work you can easily undo the operation.
That's a fairly common infection, but unfortunately the usual tool doesnt have that in it's changelog, and the next tool is not one I would suggest you use without instruction from a pro.
Don't use Norton and AVG toghether or you will have all sorts of problems - delete one Norton would be my choice.
